    Adds a line segment to the path from the current point to the beginning of the current sub-path,
    (the most recent point passed to <span class="methodname"><a href="cairocontext.moveto.html" class="methodname">CairoContext::moveTo()</a></span>),

    The behavior of close_path() is distinct from simply calling
    <span class="methodname"><a href="cairocontext.lineto.html" class="methodname">CairoContext::lineTo()</a></span> with the equivalent coordinate in the case of
    stroking. When a closed sub-path is stroked, there are no caps on the ends of the sub-path.
    Instead, there is a line join connecting the final and initial segments of the sub-path.
